Alesis S4 Quadrasynth 90's Polyphonic 1U Rack Mount Synthesiser Sound Module

The S4 is the rack-mount version of the QuadraSynth. It's a 64-voice digital synthesizer with a whopping 16 MB of sample ROM, and was the first synth to offer the ADAT Optical Digital interface. It also featured the same multi-effects processor as the QuadraVerb 2, drum kits based on the D4 drum module, 4 assignable control knobs, one PCMCIA card slot, 48kHz clock input, and 4 audio outputs.

The S4 is undoubtedly a powerful and flexible synthesiser capable of creating rich sounds - both acoustic and electronic. It uses digital additive/subtractive sample playback synthesis to create high quality stereo grand pianos, organs, strings, drums/percussion, brass, woodwinds, new and classic synth textures, and more. (Vintage Synth Explorer)

It’s Fine
Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
I was excited for low sugar. They made up for it in salt. Way too salty. Inconsistent quality from one stick to the next. Not a bad product. Not for me.

Slimy! Taste okay, but strange texture
Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12), Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
I really wanted to like these but they're really slimy! I've had Jack Links before but these are even more slimy. I normally get chomps or archer beef sticks. I would say these have the texture of the archer beef stick just a bit more slimy. Not my favorite.

Great for snacking!
Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
Being a diabetic I enjoy eating these for a snack because they won’t raise your blood sugar. Taste is fine and an excellent source of protein.

Gross Texture - Weirdly Soft
Flavor Name: Zero Sugar Beef, Size: 6oz (Pack of 12)
These are literally the nastiest possible version of a meat stick I've ever had. Bought them for the price and for lunches to take to work. As it would turn out, I couldn't give them away to family. Everyone who bravely tried it were met with the same gross, weirdly soft, texture. No matter if it was refrigerated or room temp - it was eerily soft I felt like I was eating baby food. The flavor was... Fine? I guess. It didn't wow me either way, just kinda existed. They are also pretty small, I expected more than 4in per item for the price. I thought the price was good when I thought they were bigger, but when I discovered they were smaller, the price became less worth it. Overall, I'm not sure who the target audience for these it because adults and kids alike did not like them or their weird texture.
